Godbout had one that was hex keyboard and multi digit numeric led diplays
rather than toggle switches. There was also the 8800B FP which was very 
different from the A version in implmentation.  The 8800 (and A) FP was 
a nightmare of oneshots and was wired to the backplane with a bundle of 
wires (can you say rinngggg!) plus an wire connection to the CPU card 
as well.
